Why am I getting the 'user wants to join your Dropbox team' emails?

Hi iviansur, thanks for bringing this to our attention.

It's possible that you might have had this change occur on your shared links, which could result in this behavior.

Are the people accessing the links users who accessed it previously, or new users entirely?

This will help me to assist further!

Hi Jay. Thanks for your prompt response! From the information I can track, it's a mix of both, but primarily new users. I also suspect that links generated by certain team members are triggering this behavior, though I'm not sure how to verify and confirm that.

Do the shared links have edit access or read-only access enabled?

I can only check this through the Activity menu in the admin console. Those who requested (whether intentionally or not) to be added to the team accessed links with viewer and editor access levels. I can investigate internally with the team if you need more specific details.

That would be helpful, since read-only links shouldn't have the option to join. 

Another thing to check would be if the shared links contain an rlkey in them.

Jay, all links contain rlkey. Some are read-only, while others have the 'can edit' setting. I suspect that the editable links are causing the issue. I’m unsure what those attempting to access the shared links are pressing that triggers this behavior.

Thank you Jay. Is there a way to turn off such notifications in settings? Maybe allow notifications only if someone is deliberately invited to a shared folder to collaborate? 

The notifications that you can enable or disable are visible on this page. There isn't any option to change these kinds of notifications sent to your email.

@Jay, in this case, what would you suggest to do to avoid getting such emails? We get them a lot during the day every day.
